My engagement ring, which we picked out together after going in every jewelers in Cambridge. I didn't have sapphires in mind when we started, but we found ourselves choosing between two sapphire rings. My MIL also had a sapphire ring.

Wedding ring, which matches Colin's. Even though I rarely wear it, I love that it matches and it's exactly hw I always imagined my ring would be. Plus the whole symbolism of it as the thing which Colin married me with.

My engagement ring from Jon. I lost it years ago, and he looked for a replacement at the time, but couldn't find one the same. Again, it matches his, which he keeps on his keyring, so you can take a look some time if you like. Very simple, just a twist of gold and a blue topaz, but that relationship was a big part of my life and it's a symbol of that.

My tree pendant that you gave me, it's so evocative of growing together and makes me think of you.

The pendant that matches MIL's engagement ring, which she gave me when she stopped wearing jewellery because it also sort of matches mine. I'm sorry you didn't get to meet her, she was wonderful.

(There's other stuff Colin's given me, too, and Tom, and other people, and things I have just because.)
